IMPROVEMENT IN INKING APPARATUS FOR ROTARY PRINTING-PRESSES.

Specification forming part of Letters Patent No. 142,607, dated September 9, 1873; application iiled April 19, 1873.

are caused yto vibrate more or less, so that the form-rollers also' become distributing-rollers, this arrangement being equally applicable to presses having stationary rollers with the cyl- `inder revolving under them, to those having a stationary cylinder with the rollers moving around it;l also, to those having rollers passing back and forth over a fiat distributingsurface, or to those in which the flat surface passes under the rollers; the object being to provide a cheaper and more compact and efectivewmeans of distribution, and to dispense with separate distributing rollers, by using the same rollers b'oth for inking thc form and for distribution. y

Figure 1 is a top view of a cylinder with two rollers, illustrating my invention. Fi g. 2

shows the entire circumference of the same cylinder spread out at, forming a flat distributing-surface, as required in that class of presses.

A is the bed on which the form of type is secured. B is the curved or flat distributingsurface.. C are the form and distributing rollers, of which there may be two or more, as

desired. D are the crooked tracks, which are parallel by the type-bed, but approach and recede from each other while passing by the distributing-surface. c c are the anges upon the metal roll on one end of each inking-roller. These ilanged metal rolls are arranged alternately, one upon one track, the next upon thel opposite track, and so on through any number of rollers, so that while one inking-roller is traveling to the right the next is traveling to the left,`by which means. a thorough distribution is effected.

It has not been deemed necessary, in the drawings, to show the supports or the driving mechanism, for these are all of the ordinary construction and arrangement.

I claim as my invention- The combination and arrangement of two tracks, D D, straight and parallel, each side of the type-bed A, but crooked each side of the distributing-surface B, with two or more rollers, C, having flanges c c on their alternate ends, so that, on the straight tracks, these rollers ink the form, and on the crooked tracks vibrate 'to distribute the ink, substantially as herein set forth.

EDWIN ALLEN.
